/* Embeds for the free tools. Added to every tool page by scripts/tools-embed.cjs, after tool-theme.css.
   Two parts:
   1. "Embed this tool" section on the tool page (code box, options, preview).
   2. Embed view: the same page opened as /tools/<tool>?embed=1 inside another site's iframe. The inline
      NC-EMBED script in <head> adds html.nc-embed before first paint; this hides everything but the
      tool itself (upload card + readout). Hidden parts stay in the DOM, so each tool's app.js still finds
      every element it expects. Colours are tool tokens only, so both themes work. */
